It has been solved current low temperature and has preserved the open the door internal large refrigeration capacity's of rear cabinet loss of case, and it opening the door to receive in the rear cabinet of closing the door gets into the influence of steam and expand, and atmospheric pressure reduces to being less than external atmospheric pressure, causes the phenomenon of can't opening the door. This case is preserved to low temperature with pressure balance device, the power distribution box comprises a box body, the door body and pressure balance device, be provided with one section airflow channel in the foaming layer of the box disjunction gate body, pressure balance device includes one -way rubber valve, airflow pipeline and rubber retainer plate, one -way rubber valve is fixed in among the airflow pipeline, airflow pipeline sets up in airflow channel and link up the inner wall of foaming layer and the outer wall of the box disjunction gate body, airflow pipeline's both ends are fixed through the rubber retainer plate respectively, pressure balance device sets up in the upper portion of box, one -way rubber valve is fixed in airflow pipeline's middle part, and and airflow pipeline sealing connection.
Description
Technical field
This utility model is related to technical field of refrigeration equipment and in particular to a kind of cryopreservation with air-pressure balancing device
Case.
Background technology
In the air atmospheric pressure also difference under different temperatures.Temperature is higher, and air expanded by heating rises faster, air pressure
Lower.In the use of refrigeration plant, after refrigeration product opens the door, cause the loss compared with High cooling power in casing, hotter gas enter
Casing, being subject in rear cabinet of closing the door opens the door enters the impact of steam and expands, and air pressure decreases below external atmosphere pressure, and causing cannot
Enabling phenomenon.
Utility model content
The purpose of this utility model is for above-mentioned deficiency, proposes to pass through using air pressure balance air-flow one-way flow principle,
The pressure differential producing in rapid process of refrigerastion raising middle flask inside and outside can be balanced, prevent phenomenon of cannot opening the door, can effectively pin cold again
A kind of cryopreservation case with air-pressure balancing device of amount.
This utility model specifically adopts the following technical scheme that：
A kind of cryopreservation case with air-pressure balancing device, including casing, door body and air-pressure balancing device, described casing
It is provided with one section of gas channel, air-pressure balancing device includes unidirectional rubber valve, airflow pipeline and rubber in the foaming layer of OR gate body
Glue ring for fixing, unidirectional rubber valve is fixed in airflow pipeline, and airflow pipeline is arranged in gas channel and insertion foaming layer
Inwall and the outer wall of casing OR gate body, the two ends of airflow pipeline are fixed by rubber ring for fixing respectively.
Preferably, described unidirectional rubber valve is towards the inner side of casing.
Preferably, described air-pressure balancing device is arranged at the top of casing.
This utility model has an advantageous effect in that：This has the cryopreservation case of air-pressure balancing device, works as ambient pressure
More than case internal gas pressure formula, outside air enters in cartonning by unidirectional rubber valve, and rapid equalisation case internal gas pressure is it is ensured that door body is normal
Open；When starting rapid refrigeration in case, in case, pressure is more than external atmosphere pressure, and unidirectional rubber valve pins cold air and will not leak outside,
Ensureing that cold does not run off guarantees to be incubated.

Specific embodiment
With specific embodiment, specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in figures 1 to 6, a kind of cryopreservation case with air-pressure balancing device, including casing 1, the gentle pressing of door body 2
Weighing apparatus device 3, is provided with one section of gas channel in the foaming layer 7 of casing 1 OR gate body 2, air-pressure balancing device 3 includes unidirectional rubber valve
Door 4, airflow pipeline 5 and rubber ring for fixing 6, unidirectional rubber valve 4 is fixed in airflow pipeline 5, its unidirectional rubber valve 5 direction
The inner side of casing 1, airflow pipeline 5 is arranged in gas channel and the inwall 8 of insertion foaming layer and the outer wall 9 of casing OR gate body,
The two ends of airflow pipeline 5 are passed through rubber ring for fixing 6 respectively and are fixed, and air-pressure balancing device 3 is arranged at the top of casing 1, unidirectional rubber
Glue valve 4 is fixed on the middle part of airflow pipeline 5, and is tightly connected with airflow pipeline 5.
As shown in fig. 7, the operation principle of air-pressure balancing device is：During normal refrigeration, the temperature inside the box is low, belongs to high-pressure side,
High-pressure side gas flows through A side, and air-flow is want at the extruding unidirectional rubber valve doorway all fallen over each other by B side, so that valve port is also come more
Little last closure, cold is locked in box house.After opening the door, a large amount of colds run off, and a large amount of steam enter in cartonning, balance case
The interior pressure with atmospheric pressure, here is closed behind the door, and the temperature inside the box raises and produces low pressure, and B side gases at high pressure pass through unidirectional rubber when the time comes
Valve port pours in the case of A side, pressure in tandem-driving bogie.
This air-pressure balancing device is applied in refrigeration product more than 300 liters for the capacity, can greatly facilitate and freeze
Journey breaker in middle door, it is to avoid because the poor impact that is stressed leads to not open the door.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above,
Change, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model, also should
Belong to protection domain of the present utility model.
